**Core Concept**
Primary health care (PHC) is a holistic approach to health care that emphasizes community involvement, accessibility, and comprehensive services. It focuses on preventing and treating health problems at the local level, rather than solely relying on specialized care.

**Why the Correct Answer is Right**
The correct answer is **D**, as it does not align with the principles of primary health care. The World Health Organization's (WHO) definition of PHC emphasizes the importance of health promotion, disease prevention, and treatment of common health problems at the community level. Option D likely refers to a specialized or tertiary level of care, which is not a core element of PHC.

**Why Each Wrong Option is Incorrect**
* **Option A:** Health education is a fundamental component of PHC, as it empowers individuals and communities to take control of their health and make informed decisions.
* **Option B:** Community participation is essential in PHC, as it fosters a sense of ownership and accountability among community members.
* **Option C:** Essential health services, such as immunization, maternal and child health care, and disease surveillance, are critical components of PHC.

**Clinical Pearl / High-Yield Fact**
A key principle of PHC is that health care should be accessible, comprehensive, and community-driven. This approach has been shown to improve health outcomes, reduce health disparities, and promote sustainable development.

**Correct Answer: D.**
